摘要

提出了基于SPECAN处理的宽场景聚束式SAR成像算法.首先对距离Dechirp后的信号在方位上作谱分析(SPECAN)处理消除方位模糊并对信号支撑区进行伸缩与平移变换

二次相位补偿后选择合适的插值方法恢复信号理想支撑区

最后二维IFFT成像.讨论并给出了算法对脉冲重复频率选择的限制.仿真实验验证了该方法的有效性.

Abstract

This paper presents processing algorithm for wide-swath spotlight SAR data processing based on spectram analysis (SPECAN).The first step of the proposed algorithm implements SPECAN processing to range dechirped signal.This operation can eliminate azimuth spectrum folding effect and migrate and scale the azimuth data support.Then compensates azimuth quadratic phase and recovers the ideal data support via appropriate interpolation.Finally focuses image with a two-dimensional inverse Fourier transform.Discussed and gave the restriction on the pulse repetition frequency (PRF).Experiments confirm the validity of the presented algorithm.
